非线性增光子热态的非经典特性
Nonclassical properties of nonlinear photon-added thermal state
摘要
Abstract
According to the nonlinear Jaynes-Cummings model which describes the interaction of a trapped ion with a standing wave laser field,a new quantum state,so called nonlinear photon-added thermal state,is introduced.The effect of Lamb-Dicke parameter,temperature and phase of the standing field on the nonclassical effects of the quantum state is studied by using the method of theoretical analysis and numerical calculation.The results show that the change of Mandel factor of nonlinear photon-added thermal state with temperature has a minimum.The larger the Lamb-Dicke parameter is,the stronger nonclassical effect of the nonlinear photon added thermal state is.In addition,the initial phase of the standing wave field has a significant effect on the nonclassical effects of the state.关键词
